Core Flight System : Framework : Operating System Abstraction Layer

This repository contains NASA's Operating System Abstraction Layer (OSAL), which is a framework component of the Core Flight System.

This is a collection of abstractio APIs and associated framework to be located in the osal subdirectory of a cFS Mission Tree. The Core Flight System is bundled at https://github.com/nasa/cFS, which includes build and execution instructions.

The autogenerated OSAL user's guide can be viewed at https://github.com/nasa/cFS/blob/gh-pages/OSAL_Users_Guide.pdf.

Version History

Development Build: v5.1.0-rc1+dev297

Fix #836, Add Testing Tools to the Security Policy
See nasa#838

Development Build: v5.1.0-rc1+dev293

Avoids various "possible uninitialized variable" warnings for routines that utilize this API.
Renames sockaddr* structures to sa* to deconflict from structure name in os-impl-bsd-sockets.c. Adds OS_NETWORK_SUPPORTS_IPV6 to os-impl-bsd-sockets.c compilation. Renames bsd-select-stubs.c to sys-select-stubs.c. Coverage now includes all currently possible files in VxWorks build
Resolves CodeQL security warning by restricting permissions on file create.
Changes comments using "cpp" comment style to "c" style
Adds new accessor functions APIs to get version strings and return the values of string macros defined in osapi-version.h.
- The "simple" version currently OS_VERSION macro - this is the semantic version without any extra detail. This is returned by OS_GetVersion().
- The "descriptive" version in OS_VERSION_STRING macro - this has extra detail like the most recent official release. This is returned by OS_GetVersionDescription().
- The release code name, now returned by OS_GetVersionDescription().
These accessor functions are the preferred way to get the OSAL version string, from now on users should avoid using the macro definitions as it is evaluated at OSAL library compile time, rather than application compile time, and thus will remain correct in the event that OSAL is relinked without recompiling the application. Adds osapi-version.c to implement these 3 calls and associated coverage test. This allows the version.c file to be auto-generated in the future.
See nasa#835

Development Build: v5.1.0-rc1+dev280

Makes tests skip after getting their first not implemented error.
Updates stub helpers to match the behavior of calling the default implementation stub macro (NULL VA list)
Removes redundant logic and assignment to fix static analysis warnings
Truncates at the end of the logic flow for socket name as opposed to possibly 3 different locations. Fixes static analysis warning.
Renames timer_id in unit tests to local_timer_id to avoid conflicts
Removes all deprecated elements
No behavior change. Renames UT_Stub_CheckForceFail to UT_Stub_CheckDefaultReturnValue, also only sets Value if not NULL (can pass in NULL value doesn't matter)
See nasa#830

Development Build: v5.1.0-rc1+dev262

Adds test cases for OS_ObjectIdFinalizeDelete, OS_DeleteAllObjects, and others to get 100% line and function coverage on VxWorks and shared/portable layers.
Ensures APIs check for NULL inputs or have documentation stating that a null value is allowed.
Adds timeout to static analysis check and adds format check. Removes old .travis.yml and updates badges in readme.
Adds Code QL analysis on push to main and pull requests (to main)
Cleans commented-out code in tests to address static analysis warnings
Initializes local variables to avoid returning uninitialized values from stubs and address static-analysis findings
Replaces two local return codes defined as uint32 with int32 to resolve static-analysis warnings
Simplifies switch statements based on previous checks. Removes unreachable, dead code to resolve static-analysis warnings
Terminates unit test macros variadic lists with NULL to address CWE-121 CodeQL warning
Adds a check to send the semaphore to avoid unreachable code
Adds a status return to OS_ConsoleAPI_Init so debug warnings will get reported correctly on errors.
Declares DummyVec as static to avoid warning and returning stack allocated memory when returning VecTbl in OSC_INUM_TO_IVEC stub
Updates types in os-impl-no-symtab.c to match latest APIs
Updates types in os-impl-no-symtab.c to match latest APIs
Fixes missing NULL terminations and applies the standard "sizeof" pattern where appropriate. No longer truncates filename in OS_ModuleInfo.
Fixes %u conversion in RTEMS so to address build warning
Create a wrapper around memchr() that mimics the non-C99 function strnlen() defined in POSIX-2008. Use this instead of strlen() whenever the string being checked either originates in or will be copied into a fixed-length array buffer. No behavior changes except if a bug causes strings to be unterminated.
No behavior change, applies the standard formatting using clang-format
See nasa#774

Development Build: v5.1.0-rc1+dev221

Fixes printf format to correctly build in RTEMS-5.
Deprecates OS_fsBlocksFree() and OS_fsBytesFree() in favor of OS_FileSysStatVolume().
Adds Security.md with instructions to report vulnerabilities.
Add UtDebug in OS_printf stub. Output the OS_printf input as a debug message from stub.
Documentation: Add note on UtTest_Add API. Nesting UtTest_Add from within an added test fails without error.
Unit Test: No more garbage characters written to test report log
Fix typo in osapi.h affecting C++ build. No other functional change
Unit Test: Rename UT_ClearForceFail as UT_ClearDefaultValue. Update the comments of UT_SetDefaultReturnValue to match the more general function.
Unit Test: Add test teardown failures to the test summary and changed the printout to use the same style as startup failures.
Unit Test: Removes no longer applicable UT_CheckForOpenSockets since the UT framework resets the state for each unit test.
Changes the file-create operation to read-write permissions to work on RTEMS
Unit Test: Fixes incorrect assertions in network-api-test to correctly check return values.
Unit Test: Generalizes queue timeout test to also test message queue functionality to validate settings and permissions to work with mqueues.
Implements OS_time_t with a single 64-bit tick counter rather than a split 32 bit seconds + 32 bit microseconds counter.
Unit Test: Installs the modules used in unit testing and adds removal of post-test, left-over files.
See https://github.com/nasa/osal/pulls/767

Development Build: v5.1.0-rc1+dev184

Address issues with OSAL global table management:
- use iterators whenever possible
- use an unlock key rather than task ID so OS_TaskExit() doesn't trigger a warning
- general cleanup of lock/unlock impl and remove redundant logic
- unlock global tables during create/delete
- keep threads "attached" in POSIX, so they can be joined when deleted.
No longer triggers warning with OS_TaskExit() on VxWorks (see #645)
OS_TaskDelete() on POSIX does not return until the task has actually exited (see #642)
The chmod test is now skipped on VxWorks rather than failing. The OS_FileChmod_Impl() function now returns OS_ERR_NOT_IMPLEMENTED when run on a file system that does not have permissions, which in turn causes the unit test to be skipped rather than fail.
Corrects a file handle leak.
Add parameter check to OS_SocketSendTo and adjust coverage test to validate.
Replace OS_fsBytesFree and OS_fsBlocksFree with OS_FileSysStatVolume. This new API for getting stats on file system. Uses existing OS_FileSysStatVolume_Impl call and exposes it in the public API.
When cleaning up for shutdown, delete resources that have a task/thread first, followed by other resource types. This helps avoid possible dependencies as running threads might be using the other resources. No detectable external impact; internally, the tasks are deleted first during shutdown, which only has an impact if/when tasks are actively using other OSAL resources.
The mount/unmount VxWorks implementation was not adequately checking for and handling the FS_BASED pass -through mapping type - which should be mostly a no-op. Create a mount point directory if it does not already exist when using this mapping type for consistency with POSIX.
Adds a documentation note to OS_FileSysAddFixedMap(): The virtual mount point cannot be empty - so OS_FileSysAddFixedMap(.., "/", "/") does not work but OS_FileSysAddFixedMap(.., "/", "/root") does work and allows one to open files in the root as "/root/" from OSAL applications. Mount-point directories do not need to previously exist when using OS_FileSysAddFixedMap
store taskTCB return in a void *, then cast to OS_impl_task_internal_record_t * to avoid a strict alignment compiler error
Removes the non-portable OS_PACK and OS_ALIGNED macros.
Uses the POSIX dir implementation on VxWorks 6.9. The only incompatibility is the prototype for mkdir()which is missing the second argument; this is worked around with a compatibility macro for VxWorks 6.x builds.
Translate and convert the VxWorks coverage test cases to the portable dir implementation, which benefits VxWorks7, RTEMS, and POSIX.
Fixes prototypes so they run on RTEMS by replacing uint32 with size_t
Adds OS_CHECK_POINTER macros to OS_ConvertToArrayIndex and OS_TimeBaseGetFreeRun so they can handle NULL pointers and return the correct error.
Adds access functions to convert/extract different units from an OS_time_t value - so that other code in CFE/PSP/Apps can be updated to use the access functions and thereby not break when the internal time definition changes. Replaces the int32 with OS_time_t in the "stat" structure used by the file module. Updates the pointer argument to OS_SetLocalTime() to be const. Prototype change of OS_SetLocalTime() should be backward compatible.
See https://github.com/nasa/osal/pulls/750

Development Build: v5.1.0-rc1+dev149

Document UtAssert_Message parameters, also adds "see also" note for helper macros.
Fix doxygen typo
Replace OS_BinSemFlush with OS_BinSemGive to prevent a rare race condition. Change the port numbers to be different from network test for when tests are run in parallel.
Fix doxygen format errors. Usersguide now builds without warnings.
Suppress invalid cppcheck warning in OS_WaitForStateChange
Add cppcheck static analysis workflow to osal CI
See nasa#744

Development Build: v5.1.0-rc1+dev132

Convert the OSAL Configuration Guide from docx and pdf to a markdown file.
Test Tasks do not run at 100%. Move all definitions and instantiations out of the core-test header file and reuse the already-existing single task definition.
Break up osapi-os-*.h files into units that correspond to the implementation units. Kept old header file names for compatibility.
Reworks the POSIX global lock implementation. Does not change the POSIX signal mask when locking/unlocking the global.
- Fixes a race condition.
- Adds a condition variable to the global lock structure. improves handling of tasks competing for access to the same object.
- No longer changing signal masks repeatedly/unexpectedly. May be relevant to some BSP/driver developers.
Checks return of sysconf for error and reports them. Only sets PageSize on success. If sysconf fails it provides a mechanism to avoid error propagation.
Uses errno instead of status return from clock_getres with strerror reporting.
Adds support for VxWorks 7
See nasa#690

Development Build: v5.1.0-rc1+dev109

Add support for RTEMS 5.1 in the OSAL and provides defines and necessary ifdefs so RTEMS 4.11 can continue to be supported.
Adds functional test for OS_chmod
Refactor the table array access across OSAL. Use a token concept in combination with a macro to obtain the table entry instead of indexing arrays directly. All access is then done through this table pointer. Use the full object ID in the timer call back list. Update the timer sync callback prototype. Pass the entire OSAL ID to the sync function, not just the index. This is technically an API change.
Replaces condition on forever loops to end on shutdown. Loops now exit on shutdown.
Removes obsolete printf tests that didn't work
See nasa#680

Development Build: v5.1.0-rc1+dev91

Rename UT_SetForceFail to UT_SetDefaultReturnValue since some functions that retain more than 1 value are not necessarily failing
Add a 5th timer to TimerTest functional to test the one shot (zero-length time interval) case.
Ensure all APIs use the proper type. Sizes are now size_t; these will now be 64 bits on a 64 bit platform.
Fix build issue on VxWorks 6.9 by using the 3 argument form of open(). Passing 0 as the mode solves the build issue. This parameter is ignored when not creating a file.
The address calculations now use unsigned long instead of long to ensure that all rounding and base address adjustments behave the same way in the event that the addresses lie in the upper half of memory (i.e. start with a 1 bit) which would put it in the negative range of a long type.
See nasa#662

Development Build: v5.1.0-rc1+dev75

Ensure that the handle is not NULL before invoking dlclose(). In particular the handle will be NULL for static modules. Shutdown after CTRL+C occurs normally (no segfault).
Add a "flags" parameter to OS_ModuleLoad() to indicate the desired symbol visibility:
- GLOBAL (0, the default, and matches current behavior)
- LOCAL which hides from other modules and prevents other modules from binding to symbols in this module, thereby ensuring/preserving the ability to unload in the future
- CFE should use LOCAL flag for apps, and GLOBAL flags for libraries.
See nasa#652

Development Build: v5.1.0-rc1+dev68

When OS_DEBUG is enabled, this adds a message if mutex give/take actions occur outside the expected sequence. This informs the user (via the debug console) if a lock is taken more than once or if a lock is given by a different task than the one that originally took it:

OS_MutSemTake():216:WARNING: Task 65547 taking mutex 327685 while owned by task 65547

Removes all FIXME comments
Resolves security/filename race issue by opening file and acting on descriptor by adding fstat stub
Squashed the minor recommended bugs
UtAssert macros now accept variable string arguments.The UtAssert_True wrapper around call is no longer needed to accommodate dynamic string output, thus removing the double assert. UtAssert macros will now be able to offer more information by themselves.
See nasa#639

Development Build: v5.1.0-rc1+dev60

Appliy standard formating, whitespace-only changes
See nasa#627

Development Build: v5.1.0-rc1+dev55

Deprecate OS_open and OS_creat to and replaced them with by OS_OpenCreate, which implements both functions via flags, and follows the correct OSAL API patterns.
Change use of uint32 for ID to the correct typedef. Also use ObjectIdFromInteger/ObjectIdToInteger where it is intended to convert these values to integers e.g. for the "name" fields in RTEMS.
See nasa#621

Development Build: v5.1.0-rc1+dev49

Adds an event callback mechanism to certain state changes in OSAL. This allows the CFE PSP to be notified at these points, and therefore it can add platform-specific functionality.
Correct issues involving recent OS_Milli2Ticks change.
See nasa#612

Development Build: v5.1.0-rc1+dev44

Removes OS_Tick2Micros and internalize OS_Milli2Ticks.
Adds ut_assert address equal macro.
See nasa#607

Development Build: v5.1.0-rc1+dev38

Sets Revision to 99 for development builds
See nasa#600

Development Build: v5.1.0-rc1+dev34

Move this existing function into the public API, as it is performs more verification than the OS_ConvertToArrayIndex function.
The C library type is signed, and this makes the result check work as intended.
See nasa#596

Development Build: v5.1.0-rc1+dev16

In the next major OSAL release, this code will be no longer supported at all. It should be removed early in the cycle to avoid needing to maintain this compatibility code. This code was already conditional on the OSAL_OMIT_DEPRECATED flag and as such the CCB has already tested/verified running the code in this configuration as part of CI scripts. After this change, the build should be equivalent to the result of building with OMIT_DEPRECATED=true.
See nasa#582

Development Build: v5.1.0-rc1+dev12

Removes internal functions that are no longer used or defined but whose prototypes and stubs were still present in OS_ObjectIdMap
Removes repetitive clearing of the global ID and unlocking global table and replaces these with common implementation in the idmap source file. This moves deleting tables to be similar to creating tables and provides a common location for additional table-deletion-related logic.
Propagates return code from OS_TaskRegister_Impl(). If this routine fails then return the error to the caller, which also prevents the task from starting.
See nasa#576

Development Build: v5.1.0-rc1+dev5

Adds OSAL network APIs missing functional tests as well as tests for OS_TimedRead and OS_TimedWrite
Allows separate, dynamic registration of test setup and teardown routines which are executed before and after the normal test routine, which can create and delete any global/common test prerequisites.
Adds FileSysAddFixedMap missing functional API test
See nasa#563

Development Build: 5.0.0+dev247

OS_SocketOpen() sets sock_id and returns a status when successful.
Changed timer-test to be able to use OS_MAX_TIMERS value on top of the hard-coded NUMBER_OF_TIMERS value. This will allow the test to be functional even if the OS_MAX_TIMERS value is reconfigured.
Ensures that
- All stub routines register their arguments in the context, so that the values will be available to hook functions.
- The argument names used in stubs match the name in the prototype/documentation so the value can be retrieved by name.
Adds back rounding up to PTHREAD_STACK_MIN and also adds rounding up to a system page size. Keeps check for zero stack at the shared level; attempts to create a task with zero stack will fail. Allows internal helper threads to be created with a default minimum stack size.
Avoids a possible truncation in snprintf call. No buffer size/truncation warning when building with optimization enabled.
Added new macros to osapi-version to report baseline and build number
The coverage binaries are now correctly installed for CPU1 and CPU2 as opposed to installed twice to CPU2 but not at all for CPU1.
Fixes a typo in ut_assert README and clarifies stub documentation.
See nasa#529

Development Build: 5.0.21

Command line options in Linux are no longer ignored/dropped.
No impact to current unit testing which runs UT assert as a standalone app. Add a position independent code (PIC) variant of the ut_assert library, which can be dynamically loaded into other applications rather than running as a standalone OSAL application. This enables loading UT assert as a CFE library.
Unit tests pass on RTEMS.
Resolve inconsistency in how the stack size is treated across different OS implemntations. With this change the user-requested size is passed through to the underlying OS without an enforced minimum. An additional sanity check is added at the shared layer to ensure that the stack size is never passed as 0.
Update Licenses for Apache 2.0
See nasa#521

Development Build: 5.0.20

Add "non-zero" to the out variable description for OS_Create (and related) API's.
Increases the buffer for context info from 128 to 256 bytes and the total report buffer to 320 bytes.
Add stub functions for OS_TaskFindIdBySystemData(), OS_FileSysAddFixedMap(), OS_TimedRead(), OS_TimedWrite(), and OS_FileSysAddFixedMap()
Added the following wrappers macros around UtAssert_True for commonly-used asserts:
- UtAssert_INT32_EQ - check equality as 32 bit signed int
- UtAssert_UINT32_EQ - check equality as 32 bit unsigned int
- UtAssert_NOT_NULL - check pointer not null
- UtAssert_NULL - check pointer is null
- UtAssert_NONZERO - check integer is nonzero
- UtAssert_ZERO - check integer is zero
- UtAssert_STUB_COUNT - check stub count
Using unsigned long instead of uintmax_t to fix support for VxWorks
See nasa#511 and nasa#513

Development Build: 5.0.19

Rename BSPs that can be used on multiple platforms. mcp750-vxworks becomes generic-vxworks pc-linux becomes generic-linux
New features only, does not change existing behavior. UT Hook functions now have the capability to get argument values by name, which is more future proof than assuming a numeric index.
Add functional test for OS_TimerAdd
Added functional tests for OS_TimeBase Api on OS_TimeBaseCreate, OS_TimeBaseSet, OS_TimeBaseDelete, OS_TimeBaseGetIdByName, OS_TimeBaseGetInfo, OS_TimeBaseGetFreeRun
See nasa#487 for details

Development Build: 5.0.18

Add functional tests for OS_IdentifyObject, OS_ConvertToArrayIndex and OS_ForEachObject functions.
Fix doxygen warnings
Unit test cases which use OS_statfs and run on an RTEMS IMFS volume will be skipped and categorized as "NA" due to OS_ERR_NOT_IMPLEMENTED response, rather than a failure.
The device_name field was using the wrong length, it should be of OS_FS_DEV_NAME_LEN Also correct another length check on the local path name.
For RTEMS, will not shutdown the kernel if test abort occurs.
Unit tests work on RTEMS without BSP preallocating ramdisks
If OSAL_EXT_SOURCE_DIR cache variable is set, this location will be checked first for a BSP/OS implementation layer.
Implement OS_GetResourceName() and OS_ForEachObjectOfType(), which are new functions that allow for additional query capabilities. No impact to current behavior as the FSW does not currently use any of these new APIs.
A functional test enhancement to bin-sem-test which replicates the specific conditions for the observed bug to occur. Deletes the task calling OS_BinSemTake() and then attempts to use the semaphore after this.
Employ a pthread "cleanup handler" to handle the situation where a task is canceled during the pthread_cond_wait() call. This ensures that the mutex is unlocked as part of the cleanup, so other tasks may continue using the semaphore.
Change all initial mutex locking to be a finite "timed" wait rather than an infinite wait. In all cases, the condition variable is only held for brief periods of time and should be readily available. If a task blocks for a long time, this considers the mutex "broken" and aborts, thereby avoiding deadlock. This is a "contingency" fix in that if an exception or signal or other unknown/unhandled async event occurs that leaves the mutex permanently locked.
Adds the mutex to protect the timer callback timecb resource table.
See nasa#482

Development Build: 5.0.17

OS_QueueCreate() will return an error code if the depth parameter is larger than the configured OS_MAX_QUEUE_DEPTH.
See nasa#477

Development Build: 5.0.16

Resized buffers and added explicit termination to string copies. No warnings on GCC9 with strict settings and optimization enabled.
New API to reverse lookup an OS-provided thread/task identifier back to an OSAL ID. Any use of existing OStask_id field within the task property structure is now deprecated.
See nasa#458

Development Build: 5.0.15

Changes the build system.
No more user-maintained osconfig.h file, this is now replaced by a cmake configuration file.
Breaks up low-level implementation into small, separate subsystem units, with a separate header file for each one.
See nasa#444

Development Build: 5.0.14

Adds library build, functional, and coverage test to CI
Deprecates OS_FS_SUCCESS, OS_FS_ERROR , OS_FS_ERR_INVALID_POINTER, OS_FS_ERR_NO_FREE_FDS , OS_FS_ERR_INVALID_FD, and OS_FS_UNIMPLEMENTED from from osapi-os-filesys.h
Individual directory names now limited to OS_MAX_FILE_NAME
Fix tautology, local_idx1 is now compared with local_idx2
Module files are generated when the osal_loader_UT test is built and run
Consistent osal-core-test execution status
See nasa#440 for more details

Development Build: 5.0.13

Added coverage test to OS_TimerCreate for OS_ERR_NAME_TOO_LONG.
Externalize enum for SelectSingle, ensures that pointers passed to SelectFd...() APIs are not null, ensures that pointer to SelectSingle is not null.
Command to run in shell and output to fill will fail with default (not implemented) setting.
Builds successfully using the inferred OS when only OSAL_SYSTEM_BSPTYPE is set. Generates a warning when OSAL_SYSTEM_BSPTYPE and OSAL_SYSTEM_OSTYPE are both set but are mismatched.
See nasa#433 for more details

Development Build: 5.0.12

Use the target_include_directories and target_compile_definitions functions from CMake to manage the build flags per target.
Build implementation components using a separate CMakeLists.txt file rather than aux_source_directory.
Provide sufficient framework for combining the OSAL BSP, UT BSP, and the CFE PSP and eliminating the duplication/overlap between these items.
Minor updates (see nasa#417)

Development Build: 5.0.11

The more descriptive return value OS_ERR_NAME_NOT_FOUND (instead of OS_FS_ERROR) will now be returned from the following functions (): OS_rmfs, OS_mount, OS_unmount, OS_FS_GetPhysDriveName
Wraps OS_ShMem* prototype and unit test wrapper additions in OSAL_OMIT_DEPRECATED
